A pesar de las similitudes cristaloquímicas entre los iones de cobre y los de plata, no existe ningún óxido mixto de cobre y plata ni natural ni sintético. En este trabajo se presenta la síntesis a bajas temperaturas del primer óxido mixto de cobre y plata, de fórmula Ag 2 Cu 2 O 3 (tetragonal, a=5.8857(3)Å, c=10.6868(7)Å, grupo espacial I41/amd, Z=4). Este óxido posee una estabilidad térmica superior a los correspondientes óxidos de cobre y de plata. Contiene cadenas de iones Cu(II) cuadrado-planos que alternan con cadenas en zig-zag de Ag(I) con coordinación lineal.Palabras clave: Cobre, oxígeno, plata, estructuras estado-sólido, superconductores. Synthesis and Characterization of Ag 2 Cu 2 O 3 , the first silver copper oxide.Despite the crystal-chemical similarities between copper and silver ions, there is no known silver copper oxide, neither natural nor synthetic. In this work, we present the synthesis at room-temperature of the first silver copper oxide of formula Ag 2 Cu 2 O 3 (tetragonal, a=5.8857(3)Å, c=10.6868(7)Å, space group I41/amd, Z=4). It should be noted that the thermal stability of this new oxide is enhanced with respect to Ag 2 O or even CuO . The structure consists of alternating chains of edge-sharing square planar Cu(II) and zigzag chains of linearly coordinated Ag(I) ions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
